Police hope new forensic testing techniques might help solve one of South Australia's high-profile murder mysteries.

Advances in technology have triggered a reopening of the 1983 abduction case of Louise Bell.

The 10-year-old girl was taken from the bedroom at her Hackham West home in Adelaide in January 1983.

No body has never been found, but police are convinced she was murdered.

A Port Lincoln prison inmate has been questioned and is having his DNA tested.

The man, who cannot be identified publicly, is believed to be serving a lengthy sentence for child sex offences.

Police say the testing will need to be further refined, before any conclusions can be drawn.

Detective Acting Superintendent Denise Gray of SA Police says authorities do not want to give the girl's family false hope.

"While current forensic testing initially appears positive or encouraging, I don't want to raise the hopes of Louise's family unnecessarily," she said.

Police will not say if the suspect owned a nearby house which was searched intensively back in 1991.

But they have ruled out Raymond John Bolte, previously known as Raymond John Geesing, who was convicted of Louise Bell's murder in 1984, but later released from jail after the conviction was overturned.
